一种“勺形”全髋置换外侧入路

A Modified True Lateral Approach to the Hip

本文介绍的改良勺形外侧切口,是利用了臀中肌和股外侧肌的功能的连续性和厚实的月牙形附着于大转子上。臀中肌并未切除或劈开,而是作为一个单元与臀小肌一同活动。这有利于臀中肌的再附着回去,并帮助保护外展肌。同时由于体位的灵活性,术中仅需三名术者即可完成全髋置换手术。

We describe a modified true lateral approach to the hip which exploits the functional continuity of gluteus medius and vastus lateralis and their dense crescentic attachment to the greater trochanter. The gluteus medius is not incised or splited but is detached and mobilised with gluteus minimus as one unit. This facilitates reattachment of the gluteus medius and helps to preserve abduct function. At the same time, according to the flexibility of the patient position during the operation, only three surgeons can perform the total hip replacement.
